  1. ENVR 115: Introduction to Sustainable Development September 18, 2007 Fall 2007

  2. Agenda • Introduction to course and expectations • Focus of this course is poverty reduction through sustainable development • Intellectual underpinnings • Challenges of sustainability

  3. COURSE DETAILS

  4. Logistics of Distance Education • Video is a live streaming feed • Chat room is monitored during class • Class starts promptly at 5:30 • Waiver forms for video • All information on course website • http://courses.dce.harvard.edu/~envre115

  5. Technical Details • Classroom microphones are always on • Streaming lecture video • Videos are password protected after third week • Harvard University ID number and PIN • Technical requirements to view streaming video • http://www.extension.harvard.edu/2007-08/DistanceEd/reqs/

  6. Textbook & Readings • Required Text • Rogers, Peter P., Kazi F. Jalal, and John A. Boyd, An Introduction to Sustainable Development (Pilot Edition) Harvard University Press, 2006 • Available at the Harvard COOP, Amazon.com (both new and used) • On reserve in the Grossman Library • Additional readings will be posted on the course website as PDFs

  7. Economic Literacy • There is no formal economics prerequisite for this course but students benefit by understanding basic economic concepts before environmental economics lectures on Oct. 13th • Review the list of economic terminology posted on the website. If there are terms you are not familiar with you can review “Guidelines for Preparing Economic Analyses” by the US EPA • http://yosemite.epa.gov/ee/epa/eed.nsf/webpages/Guidelines.html

  8. Student Assessment

  9. Participation • Student biographies let us get to know you • Actions that count towards your participation grade • In-class comments and questions (real & virtual) • Discussion board for course material • SD news opinions • Student presentation day

  10. Homework • Assignments will be posted on the website • First assignment is due next Tues • Experimenting with online assignment submission • Always save a copy of your assignment to your hard drive • No late assignments accepted without prior arrangement

  11. Exams • Exams are in-class, close book • Distance students in the New England area take exams in class • Distance students outside of New England must arrange a proctor at least two weeks before scheduled exam dates • http://www.extension.harvard.edu/2007-08/DistanceEd/policy/exams.jsp

  12. Graduate Student Projects • Work in small teams to develop a funding proposal for an infrastructure development project that will help alleviate poverty in a low income country • Written funding proposal • Oral presentation • Debate project in class • Assessment will be based on overall group performance and individual contribution

  13. Development Project Water & Sanitation Health Clinics Agriculture Education Transportation Graduate Student Projects Maximize Social & Environmental Benefits Gender equality Improved health Food security Protect biodiversity Access to markets

  14. Sustainable Development Through Infrastructure Improvement An Example in India

  15. Example: Restoring Rajasthan’s Traditional Earthen Dams For Rainwater Harvesting And Groundwater Replenishment Source and description of project http://ecotippingpoints.org/galleries/indiarainwater.html

  16. Negative Feedback Analysis

  17. Positive Feedback Analysis

  18. Project Summary • Building johads (check dams) is not the only factor • Hill slopes are treated to stop run-off and soil erosion • Forest conservation methods have been adopted • Strong village-level organizations (gram sabhas) which tackle all issues through collective decision-making • Economic and ecologic transformation • For every Rs 100 invested in check dams the economic production in the villages has risen by as much as Rs 400 per capita per annum

  19. Some Intellectual Underpinnings ofSustainable Development (And a Disclaimer)

  20. Thomas Malthus (1766 – 1834)The Dismal Theory • Wrote “An Essay on the Principle of Population; or a View of its past and present Effects on Human Happiness; with an Inquiry into our Prospects respecting the Removal or Mitigation of the Evils” • He believed that population was held in check by “misery, vice, and moral restraint.” • …population, when unchecked, increased in a geometrical ratio, and subsistence for man in an arithmetical ratio.

  21. And yet… • There has been a six-fold increase in global population (from 1 to 6 billion) since 1798 and still be able to more or less feed the population

  22. Cornucopians“Necessity is the mother of invention” • Increase in population pressure acts as an incentive to develop new technology and produce more food • Ester Boserup concluded “that population growth naturally leads to development” • Green revolution increased grain production by 250%

  23. Basic Laws of Human Ecology First Law of Human Ecology: • We can never do merely one thing- nature is interconnected • Concept of externalities Second Law of Human Ecology: • There's no away to throw to. • Concept that all resources have a purpose Third Law of Human Ecology: • The impact (I) of any group or nation on the environment is represented qualitatively by the relation I=PAT • Expansion of the 2nd Law of Thermodynamics Garrett Hardin

  24. Ehrlich Identity: I=PAT • Environmental Impact is a multiplicative product from small changes in Population, Affluence and Technology • Mathematically represented as: (I + ΔI) = (P + ΔP)(A + ΔA)(T + ΔT) Divide through by the identity (1 + ΔI/I) = (1 + ΔP/P)(1 + ΔA/A)(1 + ΔT/T) Where ΔI/I, ΔP/P, and ΔT/T is the percentage increase in impact, affluence and technology

  25. Quantifying Impact • Example: Lead in gasoline from 1946 to 1968 in the US • Pop. increased 42% • Vehicle mile per capita doubled • Amount of lead per vehicle mile increased 81% (I + ΔI/I) = (P + ΔP/P)(A + ΔA/A)(T + ΔT/T) (1 + ΔI/I) = (1 + 0.42)(1 + 1.0)(1 + 0.81) (1 + ΔI/I) = 5.14 ΔI/I = 5.14 – 1 =4.14 Or 414% increase in lead

  26. Economics & Environmental Degradation (Kuznet’s Curve) Relationship between air pollution problems in cities and the level of development. As a city experiences development, the air pollution problems in the city increase rapidly, before stabilizing and declining as air pollution controls are implemented (Source: Based on Haq et al, 2002; Peters 2003)

  27. Sustainability • Sustainability is the term designed to bridge the gulf between development and environment • Originally came from forestry, fisheries, and groundwater • maximum sustainable cut • maximum sustainable yield • maximum sustainable pumping rate • However, even when these maxima were achieved the ecosystem was not necessarily itself sustainable • The attempt now is to apply the concept to all aspects of development simultaneously

  28. Savings is the Key to Sustainability d M KM d N KN d H KH S + + > = y y y y Savings as percentage of GNP Depreciation of Human Knowledge Depreciation of Man-made Capital Depreciation of Natural Capital > = + + • Weak Sustainability requires the sum of all forms of capital to • be constant or increasing over time • Strong Sustainability requires each component to be • constant or increasing over time

  29. 9 Ways to Achieve Sustainability • Leave everything in its pristine state or return it to its pristine state. • Develop so as to not overwhelm the carrying capacity of the system. • Sustainability will take care of itself as economic growth proceeds. • Polluter and victim can arrive at an efficient solution by themselves.

  30. Let the markets take care of it. • Internalize the externalities. • Let the national economic accounting systems reflect defensive expenditures. • Reinvest rents from non-renewable resources (weak & strong sustainability). • Leave future generations the options or the capacity to be as well off as we are.

  31. The Debate Continues • In this course our goal is to avoid the major intellectual perils at both ends of this debate. • We must evaluate what we know and have experienced and what is predictable and attempt to maximize benefits while minimizing harm • In the long run Malthus has to be right but in the short run can we rely on human ingenuity • Thus our definition of sustainability is time-bound to the near future
